Proteasome inhibitors and Cytotoxicity

Hi everybody,
I am working on proteasome inhibitors (i.e., Velcade) and cellular toxicity and right now I am looking for protocols in order to induce stress to cells, any stress! Any hints?

In our Lab, we work on Cancer cell lines. Usually we use G418 based cytotoxic stress.

Dear Tarun, thanks for your reply.
Maybe I should have been more clear. I work with Multiple Myeloma cells and I need to find out newer ways than antibiotics in order to induce cytotoxicity. The problem is my ignorance in molecular biology protocols because I am formed as a Neuroscientist! =(For example I would like to induce:
- Oxidative stress
- Mitochondrial stress
- ER stress
- Lysosomal stressHow can I?!?

Hi Luca,
Well, simvastatin can be used to induce mitochondrial stress by inducing caspase pathway. I came across a paper that reported synergistic induction of cell death by the combination of simvastatin and doxorubicin. (Check this: Br J Pharmacol. 2004 November; 143(6): 715–724)
Kind Regards,

Well, THANK YOU!
It looks like it induces apoptosis by activation of mitochondrial caspase 9 in lymphoma and myeloma cells: that’s perfect.
Now I just have to look for the others stressors… -
HI
oxidative stress coude be applied by using H2O2 in certain concentration .
if you search yhe web you can find the exact concentration .
good luck
